App Description
The best and worldwide famous BETERAMP TUBE BIAS CALCULATOR. This app is a 3 awards winner by the Vintage Electronics Magazine and the London University of Electronics. Get the most accurate values to set up your tube amp properly and make it safe and sounding like never before. The best thing of this app is that you can use it even when you have no INTERNET connection, wich is great as many times you can't have internet access in the same place that you are fixing or re-biasing the amp, it is so easy to use and fast. There're lots of calculators on the net but they are not as accurate, fast like this one, also they need you to be ONLINE to work so you can't always use them. This app was developed by Paco Pascual himself, recognized by the most well known electronics Universities around the world. You will need this calculator always and now it's got the best price ever, AMAZING !

p.s. probably you can find online some similar calculators, but no one has got as many tubes as this one, no one has got the accuracy of this one and THE MOST IMPORTANT THING IS no one of them you can take with you everywhere and use it where there's no internet connection, and no one has got so many different tubes on it's tube calculation list !!!
